As the industry-leading medium-duty engine, the Cummins ISB6.7L engine is recognized by fleet managers as very reliable. “Dealers and drivers know this engine will start up every morning,” says IC Bus Training Manager Greg Hooley. “It gives our customers the uptime they need to get the job done, which means all that much more when you’re delivering children to school every day.” Here’s how the ISB6.7L makes fleet maintenance easier for CE Series customers.

Fuel Economy: School systems are bottom-line conscious, which means fuel is a major expense. “The ISB6.7L in combination with the Cummins Emissions Solution System provides outstanding fuel economy and lower operating costs,” Hooley explains.

Accessibility: “The ISB6.7L is very accessible under the hood and therefore easier to maintain and repair,” explains Hooley. Critical engine check points such as coolant level, power steering fluid level, transmission fluid level and engine oil level and fill are easily reached. Mechanics and drivers can do it from a standing position without obstruction.

Power: “The range of horsepower and torque ratings matches the offerings of our other engines,” says Hooley of the engine, which has a peak hp of 260 at 2,600 RPM. “It perfectly matches any school bus’ operational needs. We have a customer base that ranges from the flatlands to the mountains, so it provides the necessary power for any of those tasks.”

Customer Support: IC Bus has more than 100 specialists trained to provide professional services on a 24/7 basis, all year long. “All of our dealers are Cummins certified so that our customers know that if they need service, they will get it and the job will be done by an expert,” says Hooley.
